应用5%杀铃脲悬浮剂防治松毛虫幼虫的试验

5%杀铃脲悬浮剂属苯甲酰脲类昆虫生长调节剂,是一种高效无公害杀虫剂。为推广生物及仿生杀虫剂,找出最佳的使用剂量,利用杀铃脲悬浮剂与化学农药20%氰戊菊酯乳油进行防治松毛虫幼虫试验,结果表明:5%杀铃脲悬浮剂1 500倍液防治松毛虫幼虫72h杀虫效果达到96%以上,与20%氰戊菊酯乳油的防治效果基本相同;但其无公害,具有对害虫天敌、人畜更安全等特点,因此更具推广性。

Experiments of Controlling Larvae of Dendrolimus pinidiatrea SC by Using 5％ Triflumuron

5% triflumuron SC which is a kind of insect growth-regulator with benzoylurea is an efficient & pollution-free pesticide.For the promotion of biological & biomimetic insecticides and to find optimal dose,experiments of controlling larvae of Dendrolimus pinidiatrea by using triflumuron SC with chemical pesticides-20% fenvalerate EC were conducted.Result shows that:insecticidal effect of 1 500 times solution of 5% triflumuron SC to control larvae of Dendrolimus pinidiatrea for 72 h reach more than 96%;its control effect is basically the same by using 20% fenvalerate EC.But it has characteristics of pollution-free,safer to natural enemies of pests,human & animal and of great worth.
